Other characteristics and features.
- Internal warning signal indicating a failure in one of the power supplies. If a failure occurs, the
“ALARM” LED on the BC2240 controller board will light up.
- Power feed circuit designed to support hot-swapping operations.
Programming jumpers.
This board has a series of internal programming jumpers (PJ). However, these jumpers are
configured at the factory and, in normal operation, do not need to be changed.
Firmware modules.
At the firmware level, this board is made up of the following modules:
- FPGA programmable device: manages the D/A converters and the communication
with TDM bus.
- Digital DSP signal processor: manages board start-up, FPGA load, IP
communications and signal processing. There are two firmware modules associated
to DSP: the loader for start-up functions and the binary file for DSP itself, that includes
the code that is executed once the board has started up.
NOTE: The three firmware files are physically stored in Flash memory associated to DSP.
The firmware versions can be brought up to date by using the ”BC2000D Firmware Upgrade”
software application.
Signal layout in the RJ45 connectors of the board.
BC2219 technical specifications.
RJ45 interface:
